Flingrabu Posted September 3, 2021 Share Posted September 3, 2021 Hi, Oftentimes I'll need to illustrate something by hand. Color of paper cream color. Once done I'll try to scan the pages. Whenever I use the Auto-Level feature on the scanned results the colors come out REALLY intense - to the point of being unrecognizable - so that even the hand-written number 3 with a circle comes out like this: https://ibb.co/k1CM70g The best i could do is to reduce the scanner to 75 DPI - then hand modify the Levels' center column left side. That comes out pretty well. But, for lots of pages, it's a lot of work. Any time I use the Autolevels, the results are seemingly unusable. What do you think is happening? Thanks!

Rick Brewster Posted September 3, 2021 Share Posted September 3, 2021 Auto-Levels is generally intended for photographs, so it will probably not work well for other purposes.

Reptillian Posted September 3, 2021 Share Posted September 3, 2021 I have managed to do histogram-based normalization though I can only get back to you on Tuesday for that as I'll be away from my normal PC. For now, you could play with curves tool or levels tool(if it exists in non-auto form). Quote G'MIC Filter Developer Link to comment Share on other sites More sharing options...

ardneh Posted September 7, 2021 Share Posted September 7, 2021 If you have the Windows Store version of paint.net: In the Windows Store version of paint.net, the directories for plugins and Shapes are different. These locations need to be created manually. First navigate to your Documents folder (this may be translated to your system language). In it, create a new folder called paint.net App Files Then create three subfolders in the new folder. These should be called: Effects, FileTypes and Shapes. The correct spelling of these folder names is essential, however Windows and paint.net will ignore the capitalization (or lack of). Quote Link to comment Share on other sites More sharing options...
